Cooking device

Abstract

A cooking apparatus to improve heating efficiency and to quickly cook food. The cooking apparatus includes a heater provided at a tray receiving food to be cooked and having a pair of terminals to supply power to the heater, and a plurality of sockets provided at a rear wall of a cooking cavity. When the tray is placed on a pair of support rails of the cooking cavity and the terminals of the heater are inserted into one of the sockets, the tray is directly heated by the heater to cook the food. The heater includes a conductive film coated on a lower surface of the tray, and first and second electrodes connected to the conductive film to be opposed to each other and connected to the terminals. The conductive film and the tray are heated by current flowing through the conductive film between the first and second electrodes.

Description

technical field [0001] The present invention relates to a cooking device, in particular to a cooking device comprising a power socket and a tray, wherein the power socket is arranged on the rear wall of the cooking cavity of the cooking device, and a heater is provided in the tray, so that Heat is generated on the tray by the heater to improve heating efficiency. Background technique [0002] Generally, a cooking device includes a cooking cavity for receiving food to be cooked and a heating device installed in the cooking cavity or in an additional chamber isolated from the cooking cavity. For example, a microwave oven as a cooking device includes a cooking chamber defining a space for cooking food therein, and a machine chamber separated from the cooking chamber, the machine chamber having a magnetron that generates microwaves. Microwaves are then introduced into the cooking cavity to cook the food. [0003] In microwave ovens, where cooking is performed only by microwave...

AI Technical Summary

Problems solved by technology

As a result, heating efficiency is reduced and sufficient thermal energy cannot be transferred to the lower surface of the food, thereby increasing power consumption

In addition, since the heat energy transmitted to the upper and lower portions of food is different from each other, the food must be turned over regularly to cook the upper and lower portions of the food evenly, thereby causing inconvenience to the user

In addition, since the temperature of a portion of the microwave oven surrounding the lower heater becomes extremely high, a cooling fan operating at a high speed must be provided in the microwave oven to cool the heated portion, resulting in unpleasant noise due to the high-speed operation of the cooling fan

[0007] In addition, since the tray separated from the lower heater of conventional cooking equipment has an uneven temperature distribution between its upper surface and the lower surface facing the lower heater, food placed on the tray cannot be cooked evenly.
